fix: persona_state SET body → canonical {pad:{pleasure,arousal,dominance}} + re-vendor Tier-3 prose (v0.19.7)

worldtree-dev landed the Tier-3 persona/memory/persona_state prose docs
(c9e59ec) — shapes that serialize as freeform Any in the OpenAPI, so the
prose markdown is their source of truth. Re-vendored docs/conversation-api-spec.md
(tolerate_drift markdown pin; worldtree-spec-rev 879cefe→c9e59ec).

Consumer alignment: --set-persona-pad / _set_persona_probe was building
{pad:[list]}, but the canonical POST /sessions/{id}/persona_state body (#317)
is {pad:{pleasure,arousal,dominance}} (named dict). Aligned the probe to the
named dict + a len!=3 guard; updated contract #2's note, the set_persona_state
docstring, and the tests. The set_persona_state wrapper was already correct
(freeform pass-through) — only the CLI probe's body construction drifted.

Suite 602 green. (Also this session: heid-code-review on the #347 slice
returned unanimous zero drift across all three panel arms.)

 |---|---|---|---|
+| 2026-07-06 | `c9e59ec` | v1.0.0b22 | **Re-vendor the prose markdown — Tier-3 consumer shapes documented.** `c9e59ec` (docs-only, OpenAPI byte-unchanged vs `879cefe`) adds `docs/conversation-api-spec.md` § "Tier 3 — Consumer-defined agents": the persona / memory / persona_state SET-body shapes that serialize as freeform `Any` in the OpenAPI (so prose is their source of truth). Drove a consumer fix: `--set-persona-pad` now sends the canonical `{pad:{pleasure,arousal,dominance}}` named dict (was `{pad:[list]}`) — #317, `v0.19.7`. Foot-guns encoded: persona.ocean single-letter `{O,C,E,A,N}` on `/agents/define` (spelled-out → 422, the #348 mismatch) vs spelled-out on `POST /characters`; memory `{embedder_version, tier3_dreaming}`, stm_* deprecated, allows_world_scope removed→422; only `valence` still 422s. `pin:`-only for the markdown; the `v0.19.7` bump rode the persona_state code fix. |
 | 2026-07-06 | `879cefe` | v1.0.0b22 | **Re-vendor OpenAPI 2.2.0→2.3.0 — Worldtree shipped #347 authored-history-write.** One new REST path-group: `POST /sessions/{session_id}/history` (the authored-history-write primitive) + the `AuthoredTurnResponse` schema (openapi path count 40→41). #347 is **OpenAPI-only** — the prose `conversation-api-spec.md` + server `conversation_api.contract.md` are byte-unchanged since the 5810a26 pin (empty `git log` delta), so those `tolerate_drift` pins stay clean; the SSE schema is unchanged (#347 is event-silent by design). **Consumer side NOT yet built** — `POST /sessions/{id}/history` is a fresh in-scope ⬜ gap in `docs/coverage-map.md` (re-opens the v1 coverage-audit with exactly one gap; Heimdall-gated hide-existence → consumer treats 404 as feature-absent). `pin:`-only, no version bump. |
 | 2026-06-30 | `5810a26` | v1.0.0b2 | **Re-pin to Worldtree's FROZEN v1 surface (#326), as part of the v1 coverage-audit.** Vendored the machine-readable artifacts — `conversation-api-openapi.json` (OpenAPI **2.2.0**, 40 path-groups) + `conversation-api-sse-events.schema.json` (11 events) — now the **authoritative drift gates** (pinned in `.corviduo-canonicals.toml`, CI-checked by `canonical_drift.py`). The prose `conversation-api-spec.md` is **byte-identical** to the v0.35.16 pin (last WT markdown edit 2026-05-31), kept as the human reference (`tolerate_drift`). b2 deltas already consumed in code: 409/503 eager turn-launch statuses (#331, v0.18.3/.4) + the unified error envelope (#328). 7 endpoints documented only in the OpenAPI, not the prose, all classified in `docs/coverage-map.md`: `admin/keys/bulk`, `admin/persona/{archive,erase}`, `admin/usage`, `embed`, `judgments`, `me/usage`.

Intervening client-facing deltas reviewed, none break our consumer: #211 agent rename (`saga`→`echo`, `actor`→`mask` — slugs only); #245 `end_user_id` persistence + memory-scope resolver; #187/#188/#219 Tier-3 define/PATCH policy (additive); `bifrost` binding field + `ephemeral_does_not_accept_bifrost` 422 now documented (the #17 surface).
